I believe he was insinuating that the brother in question has a nickname, one that has probably become so popular that it has overtaken his god-given identity, and the rest of the chapter only refers to him by his newly obtained false name.

From the context, it can be surmised that the failure to remember the name of the brother is a spontaneous lapse in memory impelled by repetitively attributing the nameless-subject in question’s nickname to his entity.

Sorry Beauregard, but girlfriends? I first would have to ask which one, at which point every other brother would have ridiculed him for being a wifed up pussy. We had to know FULL name, hometown, pledge class, major and minors, big and little brothers, and hobbies on command. We were also required to obtain several other pieces of pertinent information which make our brothers the men that they are, but the ones I spoke of were clearly memorized in order to use as a redirecting rush tool as well well as knowing the best parts of the men we wished to call our brothers. None of which included who their fucking girlfriend was because obviously she most likely had a shelf life.

as a pledge class as a whole, we all got punished for one person’s fuck up, but you were totally responsible for one other brother in your pledge class (pledge buddy), so that you knew where he was at all times, knowing which class and which building he’s in. Other houses don’t do that?
